Auto Setting

The blower motor turns ON. The IPM automatically controls the blower speed. The driver may override the automatic blower control by pressing the fan speed switch.

The IPM evaluates the information supplied by the following components:
^ The heater and the A/C control
^ The network of sensors

The IPM determines which one of the following modes is required:
^ MID/FLOOR
^ MID
^ FLOOR

The IPM energizes the mode actuator to command the program-determined mode.

The information that is supplied to the IPM determines whether the system will draw the outside air in, or recirculate the inside air.
